"Up until now, there have been two characters that seem to be based on Lamia. Both of them are also, not ironically, voiced by Lamia's voice actress, Kaori Shimizu, using a similar voice and tone:
* Signum from the animated Magical Girl Lyrical Nanoha series, where many of the Angelg's attacks are similar to Signum's spells. They also share similar backgrounds and personalities, in that Signum was once a cold artificial intelligence of the Book of Darkness until she began to warm up into a better person upon meeting Hayate Yagami.
* Aschen Brödel, in the upcoming spin-off game, Mugen no Frontier: Super Robot Wars OG Saga. Like Lamia, Aschen is a battle android with green hair, and her color scheme closely mirrors Lamia's. Lastly, Aschen shares the same theme song, Ash To Ash."
